CA'R-COUPLING.-

SPECIFICATION forming part of Letters Patent No. 293,995, dated February19, 1884.

Application filed November 16,1883. (No model.)

To all whom, it may concern:

Be it known that I, FREDRIcK M. WRIGHT,

a citizen of the United States, residing at Fern Ridge, in the county ofSt. Louis and State of Missouri, have invented certain new and usefulImprovements in Gar-Couplings, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to car-couplings; and it consists in certainimprovements in the construction of the same, as herein described andclaimed.

In the accompanying drawings, Figure l is a side elevation of adraw-head and coupling having my improvements. Fig. 2is a'bottom plan ofthe same. Fig. 3 is a front view of same. Fig. 4 is a longitudinalcentral section of draw-head,&c.

A designates the draw-head, resting loosely within suitable frame-workon a crossbar, B, The hook is beveled or rounded in front, to be readilylifted by the coupling-link coming in contact with it, and is formedwith a projection or shoulder, a, near its rear end, against which thelink strikes, thus closing the hook. Within the draw-head is a raisedsurface, a, with a groove, 1), in which the hook rests when coupled, theraised surface holding the link a somewhat higher than the point of thehook when the latter is closed. The draw-head has a slot, d, in the top,to allow the hook to be raised, an aperture, 6, for inserting a coupling-pin in case the hook should be broken, and a flange, e, on thebottom to bear against the cross-bar B in draft. The hook is presseddownward by a spring, f, and is secured by a bolt, f, passing through atubular formation, 00, in the casing of the draw-head, so that it isprotected from contact with the link. The rear end of the draw-head hasa pivotal connection atD with a sliding draw-bar,E,which passes rearwardthrough an aperture in one end of a box, F, firmly fastened to the car.To the rear end of the draw-bar E is fastened a plate, G, which moves onthe fixed guiderods 9, which extend through the box lengthwise and passthrough apertures in the plate.-

Four spiral springsflz, are placed on the guide rods 9, two of saidsprings being forward and two rearward of plate G, and all of saidsprings bearing against said plate,and also against the casing of box F,as shown. The said plate G has two arms, is, extending in oppositedirections through the slots in the sides of box F, said arms beingconnected with the buffing apparatus, as hereinafter stated.

Within the box F, and fixed at the rear end thereof,is an elasticbuffer, H, the same being in line with the sliding draw-bar E, for thepurpose of concussion with it. The box has a removable sliding lid, I,which-forms the bottom, and is kept closed by anysuitable device. Theguiderrods g,being passed through. the box and through a cross-beam, J,of the car, and being securedat their extremities, serve to hold the boxsecurely in place. The said box is further secured by a band, Z, passingabout it and setting against flanges m on the box, the ends of the bandbeing made fast to the bottom of the car. The draw-barE has anenlargement at its rear end,forming shoulders n, which bear against thefront casing of the box during draft.

, Two pivoted levers, K, are each connected at one end with an arm, 7.",of the plate G, the outer end of each of said levers being connectedwith a rodor bar, L, which passes through one of two fixed woodenbuffers, M, at the end of the car, between which the drawhead islocated. Each of the rods L has a cap or buffing plate, 1), atitsforward extremity, for the purpose of contact when the said rods arepushed forward. From this construction it will be seen that as thedraw-head is pushed backward in the operation of coupling, the plate Gis also moved backward, and, through the pivoted levers, moves forwardthe rods L with buffingplates 1), which are thus pushed in contact withopposite buffers, and thus protect the draw-head.

A shaft, N, is placed across'the end of the car, havingsuitablebearings, O, and connected centrally by chains 1' with the draw-head A. Theends of said shaft are squared, to receive a handle, q, used forrotating the shaft when it is desired to raise the draw-head somewhat incoupling, this being usually done by some one standing on the ground ateither side of the car. Another shaft or roller, P, is placed across theend of the car, said shaft being properly supported above the platform,and connected centrally by a chain, 8, with the coupling-hook for thepurpose of raising it. The said shaft has at each end a handle, 15, sothat it may be 5 rotated and the coupling-hook raised by a personstanding at either side of the ear. Each handle tis made, as shown,somewhat in the form of the letter S, and so constructed that when it isturned around, one end, 10, of the 10 handle, which is somewhat flat atthe extremity, binds against the platform of the car enough to retainthe shaft or roller l? in position, the coupling hook being sufficientlyraised. The link then entering the draw-head I 5 strikes the shoulder orprojection 0, when the hook is immediately closed and the coupling iseffected.

To enable a person standing on the top of the car to raise thecoupling-hook, a pulley, Q, 20 provided with a hand.-lever, a, is placedon the top, said pulley being connected with the coupling-hook by achain, '21.

I claim 1. In a car-coupling, a draw-head connected 25 with a draw-bar,E, with moving plate G, se-

cured thereto, and connected with pivoted levers K, and the rods L,provided with buflingplates 1), the parts being properly supported,substantially as and for the purposes described. 2. In combination. witha draw-head having adraw-bar, E, coupled thereto, a-box, F, plate G,moving on guide-rods 9 within the box, pivotcd levers K, connected withplate G, rods L,

provided with plates and the buffers M, the parts being properly securedin position, substantially as and for the purposes set forth.

3. In combination with a draw-head and draw-bar loosely supported, asshown, the moving plate G, having arms k, connected with levers K, whichare connected with buffing-rods L, the slotted boX F, provided with aremovable bottom, the guide-rods g, and springs h, the parts beingconstructed substantially as shown, for the purposes set forth.

4. In combination with a draw-head having a coupling-hook, a roller, P,journaled in bearings secured to the car and connected by chain with thehook, said roller being provided with the fixed handles if, each havingone armlonger than the other, and constructed to bind against the car,as herein set forth, for the purpose specified.

5. In combination with draw-head loosely supported, as shown, a rotativeshaft, N, having bearings fixed to the car, said shaft being connectedby chains with the draw-head and provided with the removable handles q,sub stantially as set forth and described.

In testimony whereof I have affixed my signature in presence of twowitnesses.
